英文摘要 | An unsymmetrical organic compound with carbazole (Cz) as donor and benzothiadiazole (BTD) as acceptor (D-pi-A-pi*-D) was designed and synthesized via simple Heck reaction. The unique crystal structure of Cz-BTD-Cz* shows a ladder-like packing mode. A two molecule pair stacks parallelly with each other in each packing unit. In each cell, one Cz moiety is connected with BTD by vinylene bond in same plane. However, the other Cz group is connected to BTD by a one-end vinyl bond in almost perpendicular position to the coplanar part of the molecule. The shortest intermolecular plane distance is 3.48 +/- 0.1 angstrom. The photophysical properties of Cz-BTD-Cz* in solution and in bulky crystalline powder state were studied. In bulk crystalline powder state, it has a red-shifted emission band peaked at 609 nm relative to that in solution, and the FWHM was reduced to only 58 run. Electrochemical properties were also investigated. (c) 2007 Elsevier Ltd. All rights reserved. |
